What I'm talking about is a widespread attitude among 'normal' people, where anyone with a whiff of too much ego about them is nearly ostracized. So much so, that it's almost a crab-bucket mentality, rather than plain down-to-earthness.
As an example, the normal American style of telling people what you're good at goes down like a lead balloon in Ireland - saying anything positive about yourself without sandwiching it in layers of self-deprecation is seen as unforgivably gauche.
And yet - despite the above - Ireland has no shortage of neolib politicians and moguls, who have rotted our infrastructure from within - such as with tax havens, a very shortsighted and shitty strategy. The have become incredibly wealthy in the process, doubling their wealth or so during the pandemic - and they get away with it because they own the media. It's as if they're invisible, and thus immune to any social pressure.
Still though, even in Ireland, where there is a strong social push-back against the greedy ego mentality, there are still people willing to sell out their environment, country, and grandmothers to get a leg up.
These people have done very well for themselves in the last couple decades, and especially well the past few years.
To further show how right you are, these people have invested considerable resources (that have paid off well) in messing up the basic needs you mention of housing, healthcare and food - and I would add media to that list.
To me, this is the core of neoliberalism, and it is a worldwide plague.
